The Mohr-Coulomb material model is contained in the Geomechanical Toolbox data item. This property supports Static Structural and Transient Structural analyses. For additional information, see Mohr-Coulomb in the Material Reference.
Yield Surface is the Mohr-Coulomb property and includes the following physical properties:
Initial Inner Friction Angle (Degree)
Initial Cohesion (Force/length2)
Dilatancy Angle (Degree)
Residual Inner Friction Angle (Degree)
Residual Cohesion (Force/length2)
In addition, once you insert the Mohr-Coulomb model, the Mohr-Coulomb - Additional Data data item displays in the Toolbox so that you can add the optional additional model Tension Rankine Yield Surface.
